CRACK-*FILLING iviAcHiNE.

- App1ication filed March 16, 1914.

To all ywhom t may concern:

Be it known that I, JOSEPH F. GonTz,-citi zen of the United States, residing at Dayton, in the county of `Montgomery and State of Ohio, have invented certain new and useful improvements in Crack-Filling 'Machines, of which the following is a specification.

My invention relates to painting and will not only be cheapened in construction but will be more efficient in use, easily and rapidly operated, substantially automatic in action and unlikely to get out of repair.

ln resurfacing old floors, it is usually found that the cracks between succeeding boards have been filled with accumulations of dirt and foreign matter, which it is desirable to remove and thereafter to fill such cracks uniformly withl a plastic material which will harden and present a surface continuous with the adjacent boards. Heretofore it has been the custom to remove such accumulations of dirt by the use of an awl, a knife or any other pointed or edged hand tool which may be employed as agouge. Such cracks are subsequently filled with plastic material by the use of a painters putty knife or some similar tool. The several operations of digging or gouging the accumulation of dirt out of the cracks, brushing and sweeping the loose particles aside, moistening or oiling the crack preparatory to receiving the plastic material and subsequently lling the plastic material thereinto have each been performed separately and by hand operations. By such method it' is practically impossible to ill the I cracks uniformly throughout.

The primary object of the present invention is to provide means for simultaneously removing the accumulation of dirt, sweeping the open seam or crack to removethe loose particles, applying oil or other liquid thereto in an economica-l manner which will not distribute the oil or liquid over the adj acent floor boards supplying a uniform quantity of plastic material throughout the Specification ofk Letters Patent.

length of the crack and pressing the material uniformly into position.

ith the above primary and other incidental objectsrin view as will more fully appear-in the specification, the invention consists of the features of construction, the

parts and combinations thereof and the mode of operation or their equivalent as herein after described andfset forth in the claims.

In the drawings Figure l is a longitudinal sectional view of the assembled machine. Fig. 2 is a bottom plan view thereof. `Fig. 3 is a `front elevation of the assembled machine. Figs. 4, 5 and 6 are detail views of the gouge or plow, by which the accumulations are removed and the conduitv by which the plastic material is supplied to the crack. Figs. 7, 8, 9 and 10 are detail views of the operative parts, showing their relation with the crack operated upon.

Like parts are indicated by similar characters of reference throughout the several views.

rEhe machine forming the subject matter hereof, is a hand tool adapted to be pushed forward with a continuous movement, while the bit or share of the gouge or plow engages in the crack in advance of the machine and the supply conduit engaging in the crack at the rear of the machine. The body of the machine as hereinafter described is of such shape and proportions as to be conveniently grasped in the hand of the operator to vform a handle for actuating the machine throughout operative movement.

Referring to the drawings, l is a conical reservoir or container for plastic material such as cement,putty, thick paint, waX or other similar material. rIhe container or reservoir l is supported at its forward end y operating parts. rilhe carrying wheels 2 are mounted upon a transverse axle 5 supported in bearings 6 projecting from the frame member 4t. Either one or both of the carry- `ing wheels 2 are provided with internal spur gears 7 by which is operated a spiral conyveyer or feed screw 8 within the reservoir or container l and a rotary sweeper or brush 9. The spiral convcyer 8 is mounted in a vbear- Cil Ving supported centrally at the smaller end of the'conical reservoir upon radial arms 11 and at its opposite end the screw 1s mounted 1n a bearing l2 in the frame member 4:. At

its forward end the shaft of the feed screw 8 carries a worm wheel 13 engaged by a worm lirvupon a transverse shaft mounted kin bearings 16 projecting from the member 4L. The transverse shaft 15 carries at its extremity a gear pinion 17 meshing with the internal gear 7 of the carrying wheel 2. In

the event that bothl carrying wheels are provided with internal gears 7, the shaft 15 will likewise be providedwith two gear Qinions 17 to mesh with the respective gearsl'?.

Supportedin bracket arms 18'projecting I from the lower oortion of the member l is va rotary sweeper'or brush 9 projecting withv inthe crack 1n thepath of the gouge -or plow and adapted to expel 'therefrom the loose particles of foreign material. VThere is carried upon the extremity of the shaft 20 of the sweeper 9s a. gear pinion'l, which also meshes with the internal gear 7 of the wheel'Q.' Thus the rotation of the carrying f lwheel 2v serves to rotate theV gear pinion to actuate the filler feeding screw 8 and simultaneously rotates the gear pinion 2l Vto operate'the rotarysweeper 9L Projecting downwardly and forwardly from the supporting member 4l and extending in yadvance 'of the sweeper 9 is a gouge 'or prod arm 22, carryingv at its extremity a detachable bit or share 23projecting within the crack opin proportion to the width and depth of the crack.L One of the carrying wheels is provided with a beveled pinion 24a with which meshes Va second vpinion 25 carried upon the extremity of a revol'uble shaft 26 extending downwardly, rearwardly and ob'- liquely in relation with the path of travel Aof the machine. The shaft 26 is supported in hearings Ycarried upon the reservoir l or in any other suitable manner.

j At its lower rearmost extremity the shaft 26 carries a revoluble sweeper or brush 27, lwhich operates to remove the debris loosened by the k9 from the vicinity of the crack.

gouge or prod bit 23, and the rotarysweeper It is to be noted that'the rotary sweeper 9 operates ih a plane coincident with the crack operated upon, while thesweeper 27 rotates in a plane angular in relation with the crack and vthe path of the machine.- Adjacent to the lrear of thereservoirl there is pivotally supported in suitable brackets A28, a rotary wheel 29, preferably of leather7 felt, fabric orsome similar material but which might be of wood or metal. The wheel 29 is a moistening or oiling wheel and projects within the crack. While `the wheel 29 may be merely a flat disk, it is preferably a wheel provided witha'centrally disposed peripheral flange, which projects within the crack,

while the lateral treadjportionsof the wheel enga-ge the floor board a-t-felther'fside'of the Y crack.- Tlrislcenstruc'tion causesthe 'periphera-l'flange to'v engage the/sides and bottom of the [craclrf with a wiping action.

IThis conduit projects from the rearf or smaller extremity ofthe reservoir l and-is preferably though not necessarily substantially V' shaped in cross sec tion. p'u'tty, cement or other substance is'placed in the reservoir l-through the hopper 33 and is" compressed therein and simultaneously forc'edrearwar'd by the action of the rotary screw conveyer 8." The'rotation of the conveyer 8 causes-f the filleri material to be discharged from' thel rear of the reservoir 1 through" the discliargeconduit 3 in the form of a ribbon of uniform density throughout, -whioh is deposited edgewise in The. lateral treadlportions of" the wheel engagingf and rotatingfup'on the adjacent floor The filler materiah' whether wax, n

the crackoperated upon. Theextremity of the discharge conduit 3 is preferably somewhat beveled asshow'n in Fig. 1 and isprovided with an overhanging' lip 34 which gages the? height; of the ribbon filler material. Thisuibbon of material "which-has been compressed to uniform densityl by the action" ofL the conveyer 8 when deposited in the crack projects somewhat abovek the level of the adjacent floor boards. To compress the ribbon of material in the crack, there is provided a spring presser arm 35, which trails behind the discharge conduit 3 and bears upon the ioor at either side of the crack. This presser arm 35 serves to force the material in the crack, and bevel it flush with lthe floor. Y

The discharge conduit 3 isV preferablyA screw threaded or otherwise detachably connected with the reservoir l, whereby conduits of differenty sizes may be substituted,

for use in cracks of different widths or l depth. When in, use, the operatorl grasps the reservoir 1 as a handleand pushes the machine forward with the kbit of the prod arm or gouge `engaging the crack inadvance and the conduit 3 engaging the crack in the rear of the machine, while the rotary brush 9 and the rotar)7 oiling device 29 engage in the crack intermediate the plow or gouge and the conduit. the rotary conveyer 8 is operated to force i the filler material rearward through the reservoir and then through the discharge conduit into the crack. It is to be noted that the screw conveyer 8 will discharge material only during the forward movement of the machine. Thus `it will be seen that the amount of material discharged will be proportionate to the length of the crack operated upon;y It is obvious that for certain classes of work, the oilingor moistening wheel 29 and either one or both of the sweep-` ers 9 and 27 may be omitted, while for new work, the prod or gouge 23 may be dis-` pensed with and only the remaining members employed.

In starting thecleaning of a crack adjacent to a wall, the machine is reversed and operated toward the same for a distance equal to the length of the machine to remove the accumulation of dirt. During this preliminary operation it is not desired to discharge filling material as the portion of the crack beneath the 'conduithas not been prepared to receive it. To render the conveyer or feeding screw 8 ineffective during each preliminary operation the gear pinions 17 are adjusted laterally upon the rshaftlt to positions out of engagement with the drive gears 7. These pinions may be keyed or splined upon the shaft or maybe secured by set screws 36,

At the iinish end vof the crack the prod y arm will engage the wall limiting the advance of the machine while the supply conduit is arrested at a point the length of the machine from the wall. The crack will thus be cleaned entirely to the wall. To fill this remaining portion. the machine is again reversed and operated in a direction away from the wall. In order that the prod will not remove the previously placed filling As the machine is advanced,

material during the final operation, the bit or share 23 of the prod arm is removed.

In lieu of `interchangeable prods or shares 23v there may be used a share such as is shown in Fig. 6 having either one or both sides yielding or flexible, whereby the share vmay be-compressed linto a narrow crack or v will automatically expand to engage the opposite sides of a crack of greater width. In such prod or share the rear edges of the flexible or yielding sides may be turned slightly any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to certain structural features, it is to be understood that the invention is not limited to any specific details, but that the means andk construction herein describedcomprise but one mode of putting the invention into effect, and the invention is therefore claimed broadly in any of its possible forms or modifications within the scope of the appended claims.
